Show HN: I made a cheap alternative to college-level math & physics tutoring https://bit.ly/3vi8RWI

Show HN: I made a cheap alternative to college-level math & physics tutoring Hi everyone! I’m the founder of Explanations (https://bit.ly/4av0O7B). I’m building a website where students can get college level math & physics help for 1/10th the cost of private tutoring. You’d type a question, and your teacher replies by drawing a Youtube/KhanAcademy-style video; and this happens asynchronously throughout the week. When I was studying at MIT, I often had to wait 40-60 minutes in line just to get 5 minutes of “help” from a TA - when I needed 1-2 hours. I understood that TAs can’t spend all their time helping me. That’s understandable. But what made me bitter was that, the school went the extra mile to ensure I don’t have the resources to learn on my own, 1. Blocking access to solutions for past problems (to prevent cheating) 2. Purposely not recording explanations to increase attendance: https://bit.ly/4aqru9A 3. Insisting that Office Hours is a 1-by-1 format even when crowded (to prevent solutions from leaking) These policies have good intentions - it’s to encourage a synchronous, in-person learning experience. But in practice, it had side-effects: 1. Help resources become inefficient - because so much material is restricted, and so much time is spent on delivering live lectures, there’d often be 40 students competing for help from 2 TAs in a 2-hour Office Hours 2. Because help resources are inefficient, it’s very hard to catch-up: once you fall behind, you have no way to review past material efficiently enough to compensate the difference - like credit card debt 3.Every day, I’d wake up, go to a lecture I don’t understand, go to Office Hours so I can hopefully ask for a review (which’d would take a few hours), realize TAs aren’t willing to do that, then realize there is nothing I can do to recover. I fell into a depression for many years, and my bitterness fueled me to work on the early versions of explanations.app It turns out that universities succeed by being prestigious, not by teaching well. To win at prestige, be highly selective (by keeping supply low), keep a huge endowment (because it affects school rankings), and hire the best researchers (not teachers). This is actually the fundamental reason for the odd incentives in higher education, and something felt wrong. So explanations.app is completely inspired by KhanAcademy and Youtube. The mystery to me was - why weren’t there more Youtube teachers & KhanAcademy videos? I believe it’s a combination of: 1. People who teach college subjects well often have better opportunities e.g. work, research 2. Lack of rewards: even Youtubers with 100K views and 10K subscribers would have at most 1-5 paying members on Patreon On the one hand, there are all these free resources, where teachers changed the world way more than they ever got rewarded for. Then on the other hand, there is private tutoring - very effective - but very expensive e.g. $100/hour for college level subjects. I believe the balanced solution is a system where lots of students pay $10/week to a few teachers who make videos, like a paid, Q&A Youtube/KhanAcademy, so it’s personalized, effective, but still affordable. There are currently 2 teachers on explanations.app - Ben & Esther - both MIT grads, teaching physics & math for subjects like linear algebra and electromagnetism. 3 students - Laquazia, Lidija and Chandra from US, Serbia and Korea joined this month following r/physicsStudents launch: [https://bit.ly/3IW984G] While explanations.app is focused on college-level math and physics, the platform is completely open for anyone to learn and/or teach. I hope you can try it :^) and give me the chance to work with you. March 27, 2024 at 09:10AM

Show HN: Onelook – Create applications by describing them in human language https://bit.ly/3PBkr68

Show HN: Onelook – Create applications by describing them in human language Hey HN! We are the team at Onelook. Demo: https://bit.ly/3Px4QUT Blog post: https://bit.ly/3vsGogM... Onelook allows users to create fully-functional applications by describing them in human language. And by fully-functional we really mean backend included. Think of it as Retool for non-technical people or Copilot to build apps. Existing tools are for technical teams and even Retool, which is a great product, requires setting up connection to databases, write queries, and call REST APIs. We understand it is impossible to create a fully-functional app just by describing it in one go. Our approach is to model the conversation between a client and a product manager. In this case, the AI is the PM. The user chats back and forth with the AI to refine the app. Thank you! https://bit.ly/3PDDbSu March 26, 2024 at 05:02AM

Show HN: Elder Dragon's Tavern, my D&D character tracker https://bit.ly/3TuQtSq

Show HN: Elder Dragon's Tavern, my D&D character tracker This has been my secret pleasure for the past four years. Ever since I started playing D&D during the pandemic, I discovered my love for role playing and storytelling, but Beyond just wasn't cutting it for me. I wanted to make my own personal character creator and tracker that I could use for my games, so I set out to build Dwarven Academy ( https://bit.ly/3TyfQmc ) and after two years of learning I decided to rebuild it all from the ground up, so The Elder Dragon's Tavern was born. Try it out at https://bit.ly/4a1j88C This is an app to build and track D&D characters automatically, online, everywhere. It is integrated into Roll20 via a Chrome extension I wrote. I made it with the aim of automating all the book-keeping required in the game; and with the intent of being able to create lots of homebrew and tweak every single little thing about my characters. I like it because it's so flexible, down to the tiniest effect detail. Well, I like it because I built it, so I am certainly biased. I used it to create all characters I played over the past years, and to play all the campaigns I joined in that time, with the Roll20 extension. It is built on top of a very simple firebase firestore database, which after years of use I've come to not enjoy particularly. Its limitations are sometimes fiddly and hidden away in obscure pieces of documentation. Sometimes it has network issues and doesn't properly push changes. I guess I chose it at the start because it was the easiest way to switch from prototyping (saving to local storage) to a cloud solution. All the stack is firebase to be honest and the rest is OK. There is no backend: it's a complete frontend-based application. Even migration code is in the frontend. I just couldn't be bothered to set up an actual backend as I wanted to write things quickly for my own enjoyment. There are security rules on the firestore interface, of course. Also, I dread social networks and marketing. I find it really draining and I don't want to invest all my time in advertising so after a first test with Dwarven Academy, I really didn't bother. As I said, I built this application mostly for myself but YOU can use it as well. It's free and available. I've also been considering adding AI to it but honestly I asked myself... would I really benefit from it? Not sure. For now it seems too much work and cost for very little added value. https://bit.ly/4a1j88C March 24, 2024 at 09:54AM

But when Anthropic dropped Claude3 Haiku and Sonnet, we saw an opportunity to use them to slash costs and get Jumprun out to all of you. We're now rocking Haiku for research and Sonnet for the final "analysis," and the results are pretty great. We even think they might be better than GPT4-Turbo! If you've got any technical questions, fire away! We're currently trying to nail down product-market fit and figure out where to focus re: features and use cases. We'd love to hear your thoughts! Thanks a ton! - Ben and Rico https://bit.ly/4alQxeB March 24, 2024 at 02:20AM

Show HN: Using LLMs to Research Reddit to Help Decide What to Buy https://bit.ly/3Vur4Ld

Show HN: Using LLMs to Research Reddit to Help Decide What to Buy Shopping online can be pretty tedious if you care about the quality of what you are buying. The time it takes can scale pretty proportionally to some combination of the value, relative importance, and complexity of the purchase. I think LLMs can help expedite and personalize the online shopping experience to a degree marketplaces just don't currently provide. I don't think anybody really wants to read the product descriptions of a bunch of products, read reviews, do pairwise product comparisons, and find the best deals across different websites? Or am I wrong? That's why I think this shopping assistant idea is pretty cool. Would appreciate any feedback on it. ty https://bit.ly/4ajilAh March 22, 2024 at 08:32AM
